EPA Postpones TSCA PFAS Reporting Period To April 2026

The U.S. Environmental Protection Agency announced on May 12, 2025, an interim final rule that would extend the dates of the reporting period for data submitted on the manufacture of perfluoroalkyl or polyfluoroalkyl substances (PFAS) under the Toxic Substances Control Act (TSCA). Under the interim final rule, the data submission period would begin April 13, 2026, and end October 13, 2026. Small manufacturers reporting exclusively as article importers would have until April 13, 2027, to report. According to EPA, the extension will allow it to develop and test further the software being used to collect data from manufacturers, "thereby providing critical feedback to EPA, including what additional guidance would be useful for the reporting community." A pre-publication version of the interim final rule, which is scheduled to be published on May 13, 2025, has been posted. Publication of the interim final rule in the Federal Register will begin a 30-day comment period.
